Two gang light switch - what am I doing wrong?

[AFT4B]

Hi,

When I wire what I believe is the live to a switch with the neutral, one light works but other one doesn't.

When I wire it like this, nighter work.

What am I doing wrong?

If you put the 3 browns together do both lights work?

Faulty switch maybe?

Try the 3 lives together as suggested but these may be switched lines rather than neutrals.

What makes you believe that is the perm live?

They don't work if I do that.

When I disconnect the switch and separate the 3 sets of wires. One marked perm live shows it has power

When I connect these two wires to a plug/ socket that light works. But I can't seem to make it work in the switch.

There are 3 wires in the light - super confused

How do you mean, it works?

Do you mean you are extending that twin and earth cable pictured in the switch box and connecting in to a power supply and the lamp in the pendant lights up?

 

[securespark]

Are you sure the neutrals are all making continuity with each other in that connector?

 

[SUNRAY]

Have you tried connecting just line or neutral from the plug?

 

[SUNRAY]

is there any chance one of these is a 2 way system?

Has this ever worked?

What have you used to verify that?


I believe the rose is connected correctly but the contrast in the pic is a little prohibitive, Can you confirm:
1, the 4 cables are connected as I've sketched.
2, the white double arrow indicates the same cable and is marked SW
3, The centre block of terminals (LOOP) is live.

Yes, sorry - that's a bad way of putting it. I meant, I know two wires run to the second light from the switch.

I've tried various methods and I don't think it's the neutrals.

Sorry, I'm not sure what you mean?

It's not a 2 way - basically, one light is in the bedroom and other one is in the loft, which is accessed from the bedroom.

Does this help?

First of all do you have any test equipment?

Multimeter - volt stick - LED or neon screwdriver?

Second, has it ever worked or is it new?
